Hello I have been using GMS 6.5 for 2 years. At the beginning i was modelling on a old version of windows (windows XP). Since i have changed my computer and that i'm working on the new windows (windows 7), i re-installed GMS and I have a lot of bugs (for example the CHD package cannot be opened or it needs a lot of time, the typeface does'nt work corectly, etc...). Do you think, it can be a problem of drivers incompatibility because of the new windows? What do i have to do? Thanks for your help Raoul
